A number of small towns in Outback Western Australia also follow UTC+09:30 rather than UTC+08. These towns include Blackstone, Irrunytju, Warakurna, Wanarn, Kiwirrkurra, and Tjukurla.

A compromise between Western and Central time (UTC+08:45, without DST), unofficially known as Central Western Standard Time, is used in one area in the southeastern corner of Western Australia and one roadhouse in South Australia. Towns east of Caiguna on the Eyre Highway (including Eucla,[22] Cocklebiddy, Madura, Mundrabilla and Border Village, just over the border into South Australia), follow "CWT" instead of Western Australian time. The total population of that area is estimated at 200 people.[23] This area did not change when South Australia introduced DST. During the Western Australian trial of DST from 2006 to 2009, this area also sets its clocks ahead one hour during summer. This time zone is not officially recognised, but is marked by official road signs. It is tracked in the tz database, the record of time zones for computers, as "Australia/Eucla".

Those are the Unofficial time zones in Australia. I am suggesting 4 official time zones in Australia:
Time zones in Australia i am suggesting are:Winter: AWST [+8h, WA], ACWST [+9h, Eastern WA], ACST [+9.5h, NT, Western QLD, SA & Broken Hill], AEST [+10h, QLD, NSW, ACT, Vic & Tas]Summer: AWDT [+9h, WA], ACWDT [+10h, Eastern WA], ACDT [+10.5h, NT, Western QLD, SA & Broken Hill], AEDT [+11h, QLD, NSW, ACT, Vic & Tas]
